Have you ever heard about palatal expander? Do you know, as patient how to deal with this appliance? This movie will answer all of your questions!
A palatal expander is a device in the field of orthodontics which is used to widen the upper jaw (maxilla) so that the bottom and upper teeth will fit together better. There are devices to achieve the similar effect of mandibular expansion or lower jaw expansion as well.This is a common orthodontic procedure. Although the use of an expander is most common in children (8%-18%), it can be, and has been, successfully used in adults too, although the effects of expansion are slightly more uncomfortable in the adult patient. The amount of correction and the age of the patient can lengthen time of desired expansion to many months. A patient who would rather not wait several months for the end result by a palatal expander may be able to opt for a surgical separation of the maxilla. Use of a palatal expander is most often followed by braces to then straighten the teeth.
It is believed that expansion therapy should be started in patients either before or during their peak growth spurt. To obtain maximal skeletal changes, the therapy is typically initiated at a very early age. Expansion therapy performed after the peak growth spurt will lead to more dental changes than skeletal which leads to tipping of buccal teeth. There are different types of expansion techniques that can be used in patients such as rapid maxillary expansion, slow maxillary expansion, implant-based maxillary expansion and SARPE.
